Hyphantria cunea is an important worldwide pest due to its destructiveness to the crops and trees. The main active component of its sex pheromone is (3Z,6Z,9S,10R)-9,10-epoxy-3,6-henicosadiene. A new synthesis of the sex pheromone from 1-bromoundecane was developed. The procedure includes 11 steps, and the overall yield is 14%. Furthermore, nucleophilic substitution of alkyl halide, partial hydrogenation with nickel boride, Sharpless asymmetric epoxidation, ring opening with HClO4, and alkylative epoxide rearrangement (invovling the ring opening of terminal epoxide and the ring-closure with K2CO3) are crucial steps.

Key words: Hyphantria cunea, synthesis of pheromone, Sharpless asymmetric epoxidation, alkylative epoxide rearrangement
